Donald Knuth On NPR

StratoFlyer writes "This morning, NPR is running an interview with Donald Knuth titled Donald Knuth, Founding Artist of Computer Science. The persistence of this man is extraordinary, if not heroic. RealPlayer and MediaPlayer feeds will be available at 10am EST, according to the NPR.org site." Indeed they are.

  2. Pretty good piece by Concern · · Score: 5, Insightful

    Knuth came across as charming, and funny, and classically geeky, re-computing the size of a piece of paper necessary for making a five-pointed star with one cut and rattling off the equation behind it, or describing his mental process behind brushing his teeth, but also clearly grounded in continuing scholarly work.

    The narrator also mentions he's "abandoned email." Interesting detail, especially as I contemplate the 995 messages in my inbox this morning (80% spam, 19% mailing lists), I am starting to wonder why I don't get around to it myself.

    Not only that, but he chose a great numbering scheme for TeX. From http://en.wikipedia.org/wiki/TeX :

    TeX has an idiosyncratic version numbering system. Since version 3, updates have been indicated by adding an extra digit at the end of the decimal, so that the version number asymptotically approaches . The current version is 3.141592. This is a reflection of the fact that TeX is now very stable, and only minor updates are anticipated. Knuth has stated that the "absolutely final change (to be made after my death)" will be to change the version number to , at which point all remaining bugs will become features.


    So it's both useful and cool.

    Someone who accomplishes something important at great risk to his own life is a hero, not someone who plods along for years at a job no matter how important his contributions.
    So what you're saying is, someone who is willing to (potentially) give up their life is heroic, but someone who is prepared to dedicate their life to a goal is not? That someone who gambles their life, knowing that they may or may not be successful and return to a 'normal' life is more heroic than someone who instead knowingly commits to spending the rest of their life, year after year, trying to achieve something?

    The other way of looking at this is that being good at mathematics is a mental illness. I'm having difficulty understanding why you and the grandparent are considering Knuth's perfectionalism a bad thing. Is he anti-social as a result? Does his perfectionism prevent him from leading a safe, furfilling, life?

    I see no evidence that it's doing any such thing. He's a brilliant mathematician and computer scientist, and that's all. The world is full of different people. It's also full of arrogant, scared, jerks who do not like differences.

    They also mention it in the TFA.

    But I hate how you refer to this as 'open source'. Can you change Knuth's books any way you want and redistribute them? Nope. So really, it is nothing like open source or free software, except for inviting collaboration.

    And collaboration did exist long before OSS. Academic peer-review has been around for a hundred years. And collaboration has always been popular in the academic world. It was uses within academic collaboration which turned ARPANET into the internet. It was the collaborative ideals of the academic world which inspired RMS to create free software.

    So, IMHO, calling this 'open source editing' or talking about 'open source science' is really putting the cart in front of the horse.
    (Not that academia hasn't been influenced by OSS/Free software, but since OSS/Free Software also originated there, that's what you call feedback, not a new and direct influence.)

    History is full of examples of geniuses that were barely balanced between the two,

    Yeah, Isaac Newton for one. See Will Dunham's book "Journey through Genius" in which he describes a disgusting little experiment Sir Isaac performed with a pointed stick and his eyeball.

    Just because someone is functional doesn't mean they're normal and not sick.

    I'd say if a person is productive in society, and happy, you're going to have a hard time convincing me that he's sick. Even Sir Isaac. This sense that somebody who is a genius is necessarily a bit sick is an attractive myth -- it consoles the great body of us that aren't blessed with genius.

    My personal Knuth story: in 1979, when I was just starting graduate school at the University of Illinois, Knuth came on campus to give three lectures as that year's Gillies Lecture.

    At the time, the second edition of Volume I had just come out, and everybody was eagerly awaiting volumes 4 through 7. The lectures were all packed, and the great man, inventor of LR parsing and author of the definitive tome on computer science, spoke on...

    typesetting and fonts.

    Don't get me wrong, the lectures were interesting, but it didn't seem all that fundamental to computer science, if you get my meaning. 25 years later, we're still waiting for volume 4 to be completed, but at least the new editions of 1-3 had nice fonts.

    The following year, Douglas Hofstadter came to campus to speak. This was fairly soon after Godel, Escher, Bach came out, so we were all excited to see what cool and interesting CS things he would lecture on. His lecture turned to be on...

    typesetting and fonts.

    I guess it was just the thing to do at that time; little did I suspect that much of the productivity of US offices in the 90's would be spent selecting fonts for documents. I guess great thinkers are just ahead of their time.

    No, actually, it's not. Having an open mind is one thing, having a mind so open your brain falls out is quite another.

    I have heard this quip before, but you are mis-using it when applying it to scientific and critical thinking. The original quote is making reference to people who will BELIEVE anything. Scientists must consider all possibilities until proven wrong.

    This means invisible elephants MIGHT exist. However, as there is no proof that they do, and no theory for why they might, a scientist will not ponder the question long.

    This also means wormholes might exist, and even though there is no evidence of them, scientists are open to the possibility because they'd fit in with other theories that are out there, and so they do consider these.

    If someone told you there were invisible pink elephants in his back yard, you would keep an open mind about that and not think that maybe your buddy had flipped his lid? Even after going out and pointing out to your buddy that these elephants left no tracks, dung, or anything else behind to show their presence, or that you could walk over every inch of his back yard and not run into one, you would still choose not to disbelieve him if he insisted they existed and were there? Seriously? That's not science or critical thinking, that's just being foolish.

    Would I disbelieve him? Of course. Would I go further and, without proof, tell him there is no way on Earth? For pink elephants -- probably so. For something much more mysterious, why bother?

    I know you keep wanting to bring up these pink elephants, however the reality is that agnostics do not worry themselves over the question of God. There is neither proof or disproof, and so it is an interesting but pointless thought experiment.

    For someone to see a lack of evidence and firmly come down against something is just as bad as firmly coming down in favor of it. This is why people often call Atheism a religion.

    In addition, I would wager that many people that refer to themselves as atheists actually mean they are agnostic, but are perhaps not familiar with that terminology. Many of my so-called atheist friends would admit they are agnostic if you questioned them about what they really think.

  17. The responses to this post are fascinating by swillden · · Score: 5, Insightful

    It amazes me how many of the responses to this post managed to so thoroughly misunderstand it, and how defensive the reactions were.

    Some posters responded by saying, essentially, "Just because he's a smart computer scientist doesn't mean I have to believe what he says about religion." This is obviously true, and a very interesting response because no one suggested that you should believe what he says about religion. What the OP was saying, for those who need it to be spelled out, is that people who try to tell others they shouldn't believe in God "because only stupid people believe in God", need to rethink their position. Not that they need to start believing themselves, but that they should admit that belief in God is not evidence of stupidity.

    The OP wasn't ridiculing unbelievers, he was ridiculing the intolerance and arrogant condescension of some unbelievers.

    The responses I found really funny, though, were the ones who jumped right in and essentially repeated the claim that people who believe in God are stupid, in a knee-jerk reaction triggered by the word "God", apparently completely oblivious to the fact that they had just been lampooned.

    The absolute best of the bunch, though, has to be the one who claimed that the fact that Knuth is Christian places his computer science research in question! That has to be the epitome of closed-minded stupidity -- to base a rejection of well-founded research on grounds of a gently-stated opinion on a non-scientific matter... mind-boggling.
